The multifunctional sealing type special-shaped bolt comprises a bolt head and a screw rod, wherein the upper end surface of the bolt head is vertically provided with an installation convex block, the installation convex block is provided with an installation hole, the lower end surface of the bolt head is provided with an annular groove surrounding the screw rod, the annular groove is internally embedded with a sealing rubber ring, the upper end of the screw rod is a polish rod section, the lower end of the screw rod is a threaded section, and the threaded section is provided with a shallow groove which is parallel to an axis of the screw rod. According to the multifunctional sealing type special-shaped bolt disclosed by the utility model, the structure is simple and reasonable, the bolt head which is left on an installation surface after the multifunctional sealing type special-shaped bolt is installed is provided with the installation hole, thus other components can be arranged on the installation surface, the use is convenient, and the multifunctional sealing type special-shaped bolt has a sealing function after being installed and can be applied to a device which has higher requirements on sealing performance; and convenience is effectively brought for disassembling operation by adding lubricating oil from the shallow groove when the multifunctional sealing type special-shaped bolt is not easily disassembled due to rusting.

Description

A kind of multifunctional containment type special shaped screw bolt
Technical field
The utility model relates to a kind of mechanical fastener, is specially a kind of multifunctional containment type special shaped screw bolt.
Background technique
Bolt is one of modal fastening piece, and it is made up of head and screw rod.It is cylindric that screw rod is, on have outside thread and can use with nut collocation.Screw bolt and nut uses jointly, can connect and fix two parts that have through hole.And traditional bolt function is single, does not possess the performance of sealing, be not suitable in the higher machine of sealing requirements, and after long-time the use, bolt is fixed together with nut because getting rusty easily, and dismounting is convenient inadequately.
The model utility content
The purpose of this utility model provides a kind of multifunctional containment type special shaped screw bolt, single to solve bolt function traditional in the prior art, the performance that does not possess sealing, be not suitable in the higher machine of sealing requirements, and after long-time the use, bolt is fixed together with nut because getting rusty easily, dismantles inadequately problem easily.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of multifunctional containment type special shaped screw bolt, include bolt head and screw rod, it is characterized in that: described bolt head upper-end surface vertically is provided with the installation projection, described installation projection is provided with mounting hole, described bolt head lower end surface is provided with the annular groove around screw rod, is embedded with sealing rubber ring in the described annular groove, and described screw rod upper end is the polished rod section, the lower end is thread section, and described thread section is provided with the shallow slot parallel with screw axis.
Described a kind of multifunctional containment type special shaped screw bolt is characterized in that: described sealing rubber ring slightly protrudes and the bolt head lower end surface.
Described a kind of multifunctional containment type special shaped screw bolt, it is characterized in that: described shallow slot is at least one, and the shallow slot degree of depth is 1-2mm.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, adopts in the bolt head upper-end surface design that projection is installed is set, and the bolt head that bolt is stayed on the attachment face after installing has mounting hole, therefore can miscellaneous part be installed at attachment face, the convenient use; Employing arranges the design of sealing rubber ring in the bolt head lower end surface, make to have sealing function after the bolt installation, can apply to in the higher equipment of sealing requirements, has enlarged its using scope; Employing arranges the design of shallow slot in the screw flight section, when not quick detachable because get rusty when bolt, can add lubricant oil from shallow slot, thereby make things convenient for disassembling section effectively.
